| Abstract: | As the Powerpc processor is embedded in the virtex5 FPGAs by Xilinx Company, the adding of em- bedded operating system VxWorks makes it possible to create a more complicated embedded platform. The interrupt handling mechanism provided by VxWorks is of high performance in reducing latency, which is accorded with the re- al time requirement. In this paper, the interrupt handling mechanism based on Powerpc440 processor is analyzed. Then, the process of interrupt handling programming is described in detail. |
